Cataract surgery,to restore
vision,consist of removing
the cataractou lens from the
eye and replacing it with a
clear artifical lens called
a lens implant or
intraocular lens(IOL)
How cataracts affect your
lifestyle?
People with catracts, even
when wearing glasses,
typically have difficulty :
Seeing in the distance or
reading Distinguishing road
signs at dusk Recognizing
colours Recognizing friends
and family at a distance
Driving at night Detecting a
catract Cataracts can be
diagnosed only by a thorough
eye examination. An eye care
practitioner must determine
whether a cataract or other
eye disorder may be
affecting a patient's
vision.
Treating Cataract
The decision to treat a
catract is reached by the
eye care practioner and the
patient together. This
decision is based on the
degree to which the cataract
is imapring vision and the
effect of the impairment on
the patient's qulaity of
life. Today's cataract
surgery is a marvel of
medical technology. Often,
it is performed as an
outpatient procedure, under
local anesthesia. In most
cases, the incision is so
small that the eye heals
rapidly with little or no
discomfort. In the surgical
procedure, the clouded
natural lens is removed,
leaving behind the lens
capsule. Next, a man-made
lens is inserted into the
lens capsule of the eye. The
man-made lens is called an
Intraocular lens, or IOL for
short. The proven procedure
offering maximum benefits to
patients is to undergo
phacoemulsification surgey
and to get a foldable lens
implanted.
Among the foldable IOLs
there are 2 options
available :
Monofocal IOLs are designed
to provide good vision at
one distance- usually far-
so most people need glasses
after surgery for close-up
activities like reading or
crafts.
The other choice is the
Multifocal IOL, which offers
proven benefits for today's
catarct patients. It is
designed to provide good
distance vision,
intermediate vision, and
near vision. Compared with
monofocal IOls, Multifocal
IOl can reduce the need for
glasses in activities like
reading, viewing text on a
computer screen, or watching
a movie.
Paediatric cataract surgery
with IOL implants to restore
best possible vision to
children with cataracts.
YAG LASER: 1064 nm cold laser used to
cut opaque lens capsules
,create iridologist in case
of Glaucoma, enlarge the
pupil and cut strands of
vitreous
Refractive errors are an
aberration of the optic of
the eye wherein light from
the object of regard is not
clearly focused on the
retina. This disability is
commonalty corrected by the
use of spectacles and
contact lenses. Thus the
patient is dependent on
these aids, for clear
vision. |
